The Kepler Challenge is a thirty-five question multiple-choice contest on the subject of astronomy, focusing on general knowledge and specific applications in that area. Intended for students in Grade 5 and 6, it is meant to introduce the basic concepts of astronomy as well as draw on past studies in the area of mathematics and science. This contest is designed to encourage interest in space science and challenge all students to develop skills of scientific reasoning and application.
